Step 1: Preheat the Oven
Preheat your oven to 400°F (200°C) if baking the meatballs. Alternatively, you can cook them on the stovetop.
Step 2: Combine Ingredients
In a mixing bowl, combine the ground beef, breadcrumbs, Parmesan cheese, parsley, minced garlic, egg, oregano, salt, and pepper. If you’re using milk for extra moisture, add it now. Mix everything together gently until just combined. Overmixing can lead to tough meatballs, so keep it light!
Step 3: Form the Meatballs
With clean hands, shape the mixture into meatballs about the size of a golf ball (around 1.5 inches in diameter). Place them on a baking sheet lined with parchment paper or directly into a skillet if pan-frying.
Step 4: Cook the Meatballs
Baking: Bake in the preheated oven for 20-25 minutes, or until they are browned and cooked through (internal temperature of 160°F/70°C).
Pan-frying: Heat a little oil in a skillet over medium heat and cook the meatballs for about 7-8 minutes on each side until browned and cooked through.
Step 5: Rest and Serve
Once cooked, let the meatballs rest for about 5 minutes. This helps retain their juices. Serve them with marinara sauce over pasta, in a sub, or as an appetizer with toothpicks!
